To all whom it may concern:

Be it known that I, DARWIN HYDE, a citizen of the United States, residing at Mount Tabor, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Brick-Dum ing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in brick or building-block dumping mechanisms.

The object of the present invention is to improve the construction of brick-mold receiving, dumping, and pallet conveying means.

Another object of the invention is the provision of means for lifting a mold or likereceiving-receptacle and turning the same into an inverted position, so as to place its contents upon a removable frame.

A further object of the invention is the provision of means for lifting the mold after it has been placed in an inverted position so as to remove the same from the pallet upon which bricks have been deposited and thence deposit said mold upon a guiding mechanism for carrying the empty mold to one side of the machine.

A still further object of the invention is the provision of means for conveying the pallet, after the bricks or building-blocks have been placed thereon, from upon a movable palletreceiving means to horizontal tracks or guides projecting rearwardly from the upper portion of the machine.

IVith these and other objects in view the invention consists in certain novel constructions, combinations, and arrangements of parts, as will behereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the claims hereto appended.

In the drawings, Figure 1 is a plan view of a mechanism constructed in accordance with the present invention. Fig. 2 is an elevated rear view of the mechanism depicted in Fig. 1, showing the same in the position assumed when a mold has been inverted and the contents deposited upon a pallet or tray carried by a movable supporting-frame. Fig. 3 is a transverse approximately central sectional view of the mechanism, showing the different parts thereof in position ready for receiving a mold, while Fig. 4 is a view taken in a similar position to Fig. 3, showing the position of the different coacting elements of the mechanism in the position which they assume when the mold is in an inverted position, the contents thereof being deposited upon'a pallet or re ceiving device, which is at this period of the operation of the machine retained in a horizontal position. Fig. 5 is a fragmentary view of the frame, in side elevation, taken on line 5 5, Fig. 2, looking outward from the center of the machine and showing the mechanism which is connected to one end of the mold-receiving device in the position assumed when the mold is inverted for depositing its contents upon a pallet. Fig. 6 is a similar view to Fig. 5, except the mold-receiving means is shown moved to an approximately vertical position and ready to move down- Ward as soon as the lifting means disengages therefrom, so as to be in position to receivea loaded mold as soon as the same is moved from its horizontal position. Fig. 7 is a fragmentary plan view of the pallet-receiving means, showing one of the slidable plates which is secured thereto for displacing a pallet and operating means for said plate.

In the construction of the present invention I have provided mold-lifting means so that the mold is turned into an inverted position and the brick which may be contained therein removed therefrom upon a pallet. Simultaneously with the depositing of the contents of the mold upon the pallet the mold is lifted vertically and deposited upon movable guides, which are carried by the frame of the mechanism for the purpose of causing the molds to drop over the side. After the bricks or building-blocks have been placed upon the pallet there is provided means for shoving the pallet from a movable receiving member, and simultaneously with the displacing of the pallet from said receiving member the mold device drops to itsnor mal position, thereby actuating fastening means which retains the pallet-receiving means in approximately a horizontal plane, permitting said receiving means to move to its normal vertical position.

For the purpose of clearly understanding the detail construction of the different coacting devices and their relative movement I will hereinafter specifically describe each device separately, mentioning generally the cooperating elements of the mechanism, so as to facilitate the receiving of a clear and com and operation of the mechanism.

Referring to the drawings by referencenumerals, 1 designates a primary frame which is provided with a pairof transverse beams 2, which are positioned upon the longitudinal connecting-beams 3 of the frame. Secured in a transverse position to beams 2 is a metallic frame 4, which is provided with integral vertically-extending bars or supports 5 5. Connecting members 6 are secured to the front of the frame, as well as to the vertical supports 5. An approximately U shaped plate 7 is secured in a vertical position to each of theconnecting means 6. A roller 8 is j ournaled up on each of the members 7 and in the front of the frame, and comparatively large rollers 9 are j ournaled upon one of the extensions of each of the approximately U-shaped members 7 and to the supports 5 near their upper end. A plate 10 is secured in a vertical position at one of its ends to the front of the frame, and its opposite end is secured to a metallic plate 11, which is secured to the side of the frame and to one of a plurality of transverse parallel beams 12,

j which are secured to the frame near the upper portion thereof. The plates 10 are employed for the purpose of forming a stop to prevent a mold from being moved out of position after the same has been placed in the machine.

A brick-making machine is positioned near the dumping mechanism adjacent to the side carrying the meshing pinions, and the loaded mold is run into position for dumping in a machine in the direction of the arrow shown in Fig. 1.

A plurality of approximately horizontal long rollers 13 are secured upon the frame in v parallel position and are employed with the rollers 8 and 9 for receiving the loaded molds. After the molds containing the bricks or building-blocks have been pushed upon the rollers 8, 9, and 13 into position within the mechanism, one end of the mold engaging the vertical rigid plate 10, said mold is in positlon for dumping.

A longitudinal shaft 14 is journaled in the sides of the frame. Mounted upon the shaft 14 is an adjustable arm 15, said arm being provided with a roller 16. The arm 15 performs the function of a cam in operating the means which turns the brick-mold.

The turning means for causing movement of the brick-mold comprises in its construc tion a horizontal rod 17, which is carried by parallel transverse beams 12 12. Pivotally mounted upon rod 17 is a pair of approximately U-shaped bars or members 18 18, which are connected by transverse bolts 18, 19, and 20. J ournaled upon the outer ends of bolt 20 are rollers 21. -Pivotally connected to a vertical standard 22, carried by the frame, is a pivotal link 23. A link 24 is pivotally connected to link 23 at one endv and is adjustably secured at its opposite end in ap proximately a central position to bolt 18. Rigidly secured to link member 24 is an angular guide 25. The guide 25 extends for wapdly and is curved inwardly at its outer 811C An auxiliary horizontal shaft 26 is journaled upon the frame parallel to shaft 14. A pinion 27 is keyed to shaft 26 outside of frame 1, said pinion 27 meshing with a pinion 28, which is keyed in a similar position to shaft 14. A pawl 29 is pivotally mounted upon the frame 1 and is normally in engagement with pinion 28. Upon the opposite end of shaft 14 to that carrying pinion 28 there is secured belt or band wheel 30. A clutch device 31 is slidably mounted upon the shaft 14 and cooperates with band-wheel 30 for causing movement of the shaft.

When rotary movement is imparted to shaft 14 through the medium of clutch device 31 and band-wheel 30, similar move ment is imparted to the pinions and shaft 26. Upon the actuation of shaft 14 movement will be imparted to member 15, which will be caused to engage link member 23, and as shaft 14 continues to rotate cam means 15 will lift links 23 and 24, thereby causing the arms 18 18, which are provided with rollers 21, to impinge against the bottom of the mold and turn the same against the moldlifting frame 32.

Before movement is imparted to link 23 through the medium of member 15 cam member 33, which is provided with roller 34, engages a projecting bar or finger 35, which is adj ustably secured to a horizontal shaft 36. The shaft 36 is journaled in bearings 37, which are secured to thefront of the frame.

A pair of fingers 38 is rigidly secured to the shaft 36. A roller 39 is j ournaled upon each of the fingers 38. When movement is imparted to shaft 36 through the medium of finger or extension 35 and member 33, rollers 39 are moved into engagement with the mold, provided a mold is in its normal horizontal position within the machine, thereby causing said mold to be retained in a comparatively rigid position within the machine until the same isengaged by the rollers 21., secured to arms 18. After movable rollers 21 have engaged the mold said mold is removed from. engagement with rollers 39, and as member 33 passes beneath member 35, through the medium of spring 40, which is secured to plate 10 and member 35, the fingers or extensions 38 are moved to theposition shown in Fig. 1, thereby placing the rollers 39 in apertured portions which are formed in the front of the frame 1. As movement is continued to be imparted to the movable arms 18, carrying rollers 21, the mold is turned upon its inner side, which rests upon extension 41 of the hinged palletreceiving frame 42, and as the rollers 21 continue to bear against the bottom of the mold, thereby holding the same against mold-lifting means 32, said lifting means, together with hinged pallet-carrying means, is turned from its normal vertical position, as depicted in Fig. 3, to the position illustrated in Fig. 4. As the member continues to rotate, its roller 16 passes from beneath link 23 and rides into engagement with guide 25, thereby permitting the arms 18 to swing backward, and when roller 16 is entirely removed from the outer curved end of guide 25 the arms 18 will assume their normal position, as is shown in Fig. 3.

The movable receiving-frame 42 is secured to the platform 44 of the frame by means of a plurality of hinges 43. WVhile the pressing of the rollers 21, which are carried by arms18, continues against the mold receiving frame 42 will be caused to pivot upon its hinges 43. I have also provided a device for positively swinging the hinged pallet-receiving table 42 into the position shown in Fig. 4 and have secured means to table 42 and vertical standard 22 for returning the table 42 to the position shown in Fig. 3, when a pallet is removed therefrom, after the bricks or buildingblocks have been deposited thereon.

The actuating means for positively causing movement of pallet-receiving means 42 comprises a curved link member 45, which is pivotally secured near its upper end to an extension 46, formed upon receiving means 42. The link 45 is pivotally connected to one end of a link member 47, which is pivotally mounted upon a bolt 48, positioned upon standard 22. Bolt 48 also provides means for securing the link 23 to the standard 22. The link 45 has a recessed or notched portion 49, which is adapted to be engaged by a pin 50, secured to link 23. Synchronous with the raising of link 23 by means of member 15 the pin 50 will engage the recessed portion 49 of link 45, thereby exerting an upward pressure upon the hinged receiving-table 42. When the link 23 is moved to its extreme upward position, the palletreceiving member will have assumed the position shown in Fig. 4.

Then the pallet-receiving frame or member 42 has been positioned as depicted in Fig. 4, a locking mechanism will secure the same in such position until the bricks or buildingblocks are deposited upon a pallet carried thereby when the machine is in operation, and subsequently with the removal of the mold from engagement with the pallet, which is in engagement with the receiving frame 42, the mold lifting member will swing into a vertical position and drop down into its normal position, as is clearly illustrated in Fig. 3. When the mold-lifting frame 32 assumes the position clearly shown in Fig. 3, the lower side of said lifting-frame will engage extension 51, which is pivotally secured to the frame at 52. An' integral right-angled extension 53 is secured to extension or trigger 51. Secured to extension 53 is a link 54, which is connected to a hook 55. A spring 56 is secured at one of its ends to extension 53, and its opposite end is secured to block 57, to which is pivotally secured the hook or catch 55. An angular approximately horizontal bar 58 is fulcrumed near its inner end at 59 to standard 22. A bar 59' is secured at 60 to the under side of pallet receiving member 42, and said member 59 is pivotally secured near its lower end to bar 58. Connected to the outer end of bar 58 at one of its ends is a spring 60, which also has its opposite end secured to frame 1. The spring at all times exerts a downward pull upon bar 58, and consequently an upward pressure through bar 59 upon the pallet-re ceiving frame 42. A pin 61 is secured to bar 59. The hook 55 is adapted to engage pin 61 for retaining pallet-receiving frame in a locked horizontal position. By the employment of spring 56 the trigger is normally retained in such a position as to be readily engaged by pin 61, when the bar 59 is caused to descend by the actuation of the different elements when the machine is in operation. When the trigger 51 is caused to move downward, thereby imparting movement to the catch 55, said catch is disengaged from pin 61, thereby permitting of upward movementto be imparted to pallet-receiving frame 42- through the medium of spring 60. Secured upon each end of the pallet-receiving frame 42 is a metallic guide-plate 62, upon which is slidably mounted a lug or plate 63, which is employed for removing the pallet 64 from the receiving-frame 42. When the pallet 64 has been removed from frame 42 by means of the slidable lugs or plates 63 and as the pallet-receiving frame 42 begins to assume its vertical position the lugs 63 will ride downupon guides 62, and when pallet-receiving frame or platform 42 is in its vertical position the slidable lugs or plates 63 will be positioned upon the lowest portion of guideplates 62.

The mold when pressed against plates 65, carried upon the sides of mold-lifting frame 32, by means of the swinging frame provided with arms 18, will cause the frame 32 to pivot at 66 upon verticallyslidable frame 67 (clearly shown in Figs. 5 and 6) and assume the position shown in Fig. 4 as the machine is operated. Simultaneous with the disengagement of member 23 by roller 16 rollers 68, journaled upon arms or extensions 69, which are adjustably secured to shaft 26, will engage integral flanges 70, secured to vertically-slidable frames 67. As the machine is operated the rollers 68 will raise the frames 67 between the parallel guides 71, and when the arms 69 have moved nearly from engageframe 42.

ment with the flanges blocks 72, which are slidably mounted within slotted portions 73 of frames 67 will engage bars 74, forming a stop for blocks 72. Links 75 are secured to blocks 72 near one end and at their opposite ends to integral angular extensions 76, which are formed upon the sides of mold-lifting frame .32. As upward movement is continued to be imparted to frames 67, which are positioned between the rods 71 upon each side of the frame, an upward movement of blocks 72 is prevented by means of stops 74. The links .75 will exert a downward pull upon extensions 76 of the mold-lifting frame 32, thereby causing the same to pivot at 66 upon the bolt which is secured near the top of the frame 67 and move the same to its normal horizontal position. When mold lifting frame 32 is in its horizontal position, I have provided an extension 77 upon each side of the frame contiguous to extension 7 6, said projection 77 being adapted to engage pins 78 for limiting movement of frame 32. When the moldlifting frame 32 has assumed the position shown in Fig. 6 and the rollers 68 have moved from engagement with the flanges of frames 67 the mold-lifting frame 32, together with said vertically-slidable frames 67, will drop to their normal position, as is shown in Fig. 3. When the frame 32 has moved to its normal position, said frame will engage the trigger 51 and through the medium thereof will release pallet-receiving frame 42 for the purpose of permitting the same to be moved to its normal vertical position. When the rollers 68 have moved from engagement with the flanges or extensions 70 of the frames 67, rollers 79, journaled upon arms 80, which are rigidly secured to arms 69, will engage the slidable plates 63, positioned upon guides 62, which are secured to When the frames 67 have assumed their normal position, thereby placing the mold-lifting frame in the position clearly shown in Fig. 3, the plates 63, through the medium of rollers 79 and arms 80, will have entirely removed the pallet upon which the bricks or building-blocks are positioned from upon the movable platform 42 and upon the guides or supporting members 81. Simultaneously with the removal of the pallet from upon the receiving frame or platform 42 the mold-lifting frame and its coacting mechanism will assume its normal position, thereby engaging the trigger 51 and releasing the catch 55, permitting the pallet -rece1v1ng frame to be moved upon its pivot and assume its vertical position. The mold-lifting frame 32 positively removes the mold from engagement with the deposited bricks or buildingblocks which are placed upon a tray or pallet, and as it swings over to its normal vertical position the empty mold is placed upon the angular guides 82, which are pivotally secured at 83 to the front of theframe. The guides 82 extend beyond the vertical planein which the front of the frame is formed for the purpose of preventing the molds from coming in contact with the front of the machine as they are'removed therefrom.

From the foregoing description it will be obvious that the mold is run into the machine upon the rollers, and thence said mold containing the bricks or building-blocks is picked up by the swinging arms and pressed against the mold-lifting frame 32. A pallet having been placed between the palletre-.

ceiving platform 42 and frame 32, as the two frames are moved to a horizontal position the bricks or blocks will be deposited upon said pallet, As the machine continues in operation the mold will be lifted vertically and subsequently thrown upon the guides 82, from which they slide from the machine. The mold-lifting frame has a swinging movement until the bricks or blocks are removed from the mold, and then said frame has a vertical movement sufficient for insuring the removal of the mold from engagement with the deposited bricks. After the mold lifting frame has been sufficiently removed from the pallet and its movable support the mold receiving frame is pivoted and thrown to a horizontal position and thence permitted to drop to its normal position upon the machine. Upon assuming its normal position said frame actuates the locking means which retains the pallet-receiving platform or frame in its horizontal position until the pallet has been removed therefrom, and upon the release of said frame 42 the same is also moved into approximately parallel position with mold receiving and lifting frame 32. The swinging arms 18 having assumed their normal position and the fingers 38, which are provided with rollers 39, being positioned as shown in Fig. 1, the mechanism is now in position for the reception of a mold, preferably containing bricks or building-blocks.

It will be apparent that the trays must be fed into the machine upon the rollers 8, 9, and 13 and that pallets must be positioned between frames 32 and 42, so as to receive the contents of the molds. As the pallets are pushed upon the guides 81 the same are removed and transferred to any place desired. From the foregoing description it will be obvious that the dumping mechanism hereinbefore described comprises a mold-turning device, a vertically-movable mold receiving and turning frame, and .a swinging pallet receiving and displacing device. The vertically-mOvable mold receiving and displacing frame constitutes a device which receives a mold which is to be dumped and carries the mold from a position at right angles to its normal position to an inverted dumping po sition and thence reversing the inverted position of the mold and bringing the same to and placing it upon means for conveying the empty mold from the mechanism.

While I have described in the foregoing description and depicted in the accompanying drawings the preferred construction of my invention, it will be obvious to one versed in the art to which this invention relates that certain alterations, modifications, and changes may be made, and I therefore reserve the right to make such alterations, modifications, and changes as shall fairly fall within the spirit and scope of the present invention.
